To all whomz't may concern:

Beat known that I,WVALTERH.-DANLELS,

a citizen of the United States, residing at Savannah, in the county/ofChathamand State of Georgia, have invented a new "and useful SeparatingTrap, of whichythe following is a specification.

The device forming the subject matter of this application is a trapadapted ;-to permit the passage of air and steam but intended to closeagainst the passage'of Water, the structure being of peculiar utility inconnection with a thermostatic air valve for the elimination of air froma Steam line.

The invention aims to provide novel means whereby the outlet may beclosed rapidly as the water rises, rather than against the rise ofwater.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that type to which the inventionappertains.

With the above and other objects in view, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that, Within the scope ofwhat is claimed, changes in the precise embodiment of the inventionshown can be made without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in vertical longitudinalsection, a device constructed in accordance with the invention, partsappearing in elevation; Figure 2 is a transverse section wherein partsappear in elevation; Figure 3 is a fragmental horizontal sect-ion.

In carrying out the invention, there is provided a tank 1 which may bevariously constructed. The tank may embody a base 2 and a top 3 securedat 4 to the base. An inlet 5 is formed in the base 2, and the top 3 hasan outlet 6. The part 3 is provided with a depending annular flange 7wherein a tubular seat 8 is held removably, by threading or otherwise,the seat forming part of the outlet 6.

A support or post 9 is mounted on the base 2. A clamp 10 is pivoted at11 to the support 9 and is held by a securing element 12 on theintermediate portion of a lever 13 carrying a float 14 located withinthe tank 1. The inner end of the lever 13 is ofiset downwardly, as shownat 15.

Standards 16 are erected on the base 2. ThestandardslG are cutaway attheir upper .ends to define transverse shoulders 17 and a thinned neck18, ineach standard.-= Upwardly extended guides 19 are disposed onopposite sides ofrthe .neck 18 of each standard 16 and are held ithereonby secur-;

ingelements 20, the lower "ends. oithe guides being received by theshoulders 17; The:

upper endsoflthe/guides '19 of-. each -stand I ard -16 are held,together in any suitable way, for instance by spacers 21 and securingelements 50.

The device includes a valve, denoted generally by the numeral 22 andincluding a stem 23 provided at its lower end with a fork 24, the armsof the fork having longitudinal slots 25. The stem 23 of the valve 22carries a head 26 whereon a disk 27 is held by a washer 28 and a nut 29or in any other suitable way, the disk 27 being made of fibre or anyother suitable, material not subject to deterioration. The disk 27 isthe part of the valve which cooperates immediately with the seat 8 whenthe valve moves upwardly.

The numeral 30 marks a lazy tongs received at its outer edges betweenthe guides 19 slidably. The end of the lever 13 is mounted pivotally inthe lower end of the lazy tongs 30. The fork 24 of the valve stem 23straddles the upper end of the lazy tongs 30. The uppermost pivotelement 31 of the lazy tongs forms a connection between the lazy tongsand the fork 24. An intermediate pivot element 32 of the lazy tongs isreceived slidably in the slots of the fork 24 and. thus, the valve 22 ismaintained in the position shown in Figure 2 of the drawings.

When water rises in the tank 1, the lever 13 is tilted, responsive tothe action of the float. The lowermost members of the lazy tongs rest onthe upper ends of the necks 18 of the standards 16 and are fulcrumedthereon. Consequently when the lever 18 tilts responsive to the float14, as the water rises in the tank, the lazy tongs 30 will be elongatedand the valve 22 will be closed with respect to the seat 8. Through theinstrumentality of the lazy tongs 30, the movement of the lever 13 ismultiplied greatly and the valve 22 will move with correspondinglyincreased speed toward and away from the seat 8. The valve 22 may belocated at considerable -distance from the nected' to the lazy tongs;and a valve car seat 8, so as to afford a good clearance at the outletport 6, a small movement of the lever 13 bringing about a' greatlyincreased 7 movement of the valve.

What is claimed is 1. A device of the class described comprising a tankhaving a seat; horizontally spaced vertical guides in the tank; a lazytongs directed throughout its length by the guides and supported by theguides; a floatoperated lever fulcrumed in the tank and connected withthe lazy tongs; and a valve carried by the lazy tongs and coacting withthe seat.

2. A device of the-class described comprising a tank; guides in thetank; a lazy tongs slidably received in the guides; means for supportingthe lazy tongs at its lower end; a float-operated lever in the tank andconried by the lazy tongs, the tank having a seat wherewith the valvecoacts.

3. A device of the class described comprising a tank; aseat carried bythe tank; a float-actuated lever in the tank; a lazy tongs assembledwith the lever; means for supporting the lazy tongs; means for guidingthe lazy tongs; 1 and a valve cooperating with the seat; the lazy tongsembodying pivot elements oneof which supports the valve, the'other ofwhich constitutes a guide whereon the valve is received slidably.

In testimony that I claim the foregoing as my own, I have hereto afiixedmy signas ture in the presence of two Witnesses.
